Class
    Foam::solvers::twoPhaseVoFSolver
 
Description
    Solver module base-class for 2 immiscible fluids using a VOF (volume
    of fluid) phase-fraction based interface capturing approach, with optional
    mesh motion and mesh topology changes including adaptive re-meshing.
 
    The momentum and other fluid properties are of the "mixture" and a single
    momentum equation is solved.
 
    Either mixture or two-phase transport modelling may be selected.  In the
    mixture approach a single laminar, RAS or LES model is selected to model the
    momentum stress.  In the Euler-Euler two-phase approach separate laminar,
    RAS or LES selected models are selected for each of the phases.
 
    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient and steady simulations.
 
    Optional fvModels and fvConstraints are provided to enhance the simulation
    in many ways including adding various sources, Lagrangian
    particles, surface film etc. and constraining or limiting the solution.
